DeepSeek has previewed its V4 model family, led by a 1.6 trillion-parameter flagship, and made a one-million-token context window the default across all its services. The weights are downloadable and self-hostable, putting frontier-scale long context in reach of smaller labs and individuals without per-token payment to a closed provider. Key facts What: DeepSeek previewed two free-to-download V4 models that can read a million tokens at once, no longer as a premium add-on but as the standard setting. When: 2026-06-29 Primary source: read the source A large language model has no persistent memory. Each time it answers, it re-reads everything in front of it — your question, the conversation so far, any documents you pasted — and that pile of text is the context. The context window is the hard ceiling on how much it can hold at once. For years that ceiling was a few thousand words, then tens of thousands. Pushing it to a million has been possible but expensive, usually sold as a special, pricey tier. DeepSeek's move is to make a million the everyday default. The family comes in two sizes. V4-Pro is the big one — 1.6 trillion parameters in total, but only about 49 billion of them switch on for any given word. That design is called a mixture of experts : instead of running the entire brain for every token, the model routes each piece of text to a small relevant subset of specialists, so it stays affordable to run despite its enormous size. V4-Flash is the smaller, cheaper, faster sibling, meant for everyday chat and quick edits, and DeepSeek says it keeps up with Pro on simpler agent tasks. Making a million-token window affordable comes down to how the model handles its KV cache — the running set of notes it stores about every previous word, which grows steadily the longer the conversation gets. At a million tokens those notes become a mountain of memory, and the model normally has to consult every note for every new word it writes. DeepSeek's approach, which they call sp

Smart speakers have spent the past few years searching for a compelling second act. Beyond music, timers, and controlling your lights, they've struggled to justify taking up space on the kitchen counter. AI promised to change that. Amazon debuted its new hardware powered by a revamped Alexa last fall, and now it's finally Google's turn. […]

A researcher found that using Anthropic’s Claude Opus 4.7, he could break into the website of Front Gate—used by every festival from Lollapalooza to Bonnaroo—and freely issue any ticket he chose.

Asynchronous Messaging with Azure Service Bus Azure Service Bus provides enterprise-grade messaging infrastructure with advanced features for reliable message delivery, ordering guarantees, and complex routing scenarios. Service Bus vs Azure Queue Storage Azure Service Bus offers enterprise messaging capabilities including: Topics and subscriptions for pub/sub patterns Message sessions for ordered processing Transaction support across operations Dead-letter queues for failed messages Messages up to 100MB (premium tier) Advanced routing with filters and actions Azure Queue Storage provides: Simple FIFO queue operations Lower cost for basic scenarios Messages up to 64KB Best for simple point-to-point messaging When to Choose Service Bus Use Azure Service Bus when you need: Publish-subscribe patterns with multiple subscribers Guaranteed message ordering with sessions Transactional message processing Message size beyond 64KB Advanced routing and filtering Integration with hybrid or on-premises systems Implementation with .NET 9 .NET 9 introduces improved performance and simplified APIs for working with Azure Service Bus: // Producer using .NET 9 with improved performance public class OrderCreatedPublisher { private readonly ServiceBusSender _sender ; public OrderCreatedPublisher ( ServiceBusClient client ) { _sender = client .

This article is part of the Comprehensive Guide to Microservices Architecture in .NET Core, Cloud and Azure series. API gateways serve as the entry point for client applications in distributed architectures, handling request routing, composition, and protocol translation. As systems grow more complex with multiple client types and backend services, choosing the right gateway pattern becomes crucial for maintaining performance, scalability, and developer productivity. This article explores two powerful API gateway patterns in .NET: the Backend for Frontend (BFF) pattern, which creates client-specific gateways, and GraphQL, which offers flexible, query-driven data fetching. Both patterns address the challenge of efficiently serving diverse clients while maintaining clean architecture and optimal performance. Backend for Frontend (BFF) Pattern Web BFF Implementation The web BFF returns detailed, enriched data suitable for desktop browsers with higher bandwidth and processing power: [ ApiController ] [ Route ( "api/web/[controller]" )] public class OrdersController : ControllerBase { private readonly IOrderServiceClient _orderClient ; private readonly ICustomerServiceClient _customerClient ; private readonly IInventoryServiceClient _inventoryClient ; [ HttpGet ( "{id}" )] public async Task < WebOrderDto > GetOrder ( Guid id ) { // Execute parallel calls to improve response time var orderTask = _orderClient . GetOrderAsync ( id ); var customerTask = _customerClient . GetCustomerAsync ( id ); var inventoryTask = _inventoryClient . GetInventoryStatusAsync ( id ); await Task . WhenAll ( orderTask , customerTask , inventoryTask ); return new WebOrderDto { Order = orderTask . Result , Customer = customerTask . Result , InventoryStatus = inventoryTask . Result , // Include additional rich data for enhanced web UI experience RecommendedProducts = await GetRecommendationsAsync ( id ) }; } } Mobile BFF Implementation The mobile BFF provides optimized, lightweight responses to min

Market research company Klue told customers that it believes the hacking group that stole their data is now deleting it. The company, however, warned about a second group of hackers wanting ransom.

While there was probably a moment when Slate’s leadership had to green-light the switch from one battery type to another, the momentum toward that decision had been building for years.

Philips Hue has announced a connectivity upgrade for its Matter-over-Thread-enabled smart bulbs that will allow them to run both Thread and Zigbee at the same time. The change means you can connect compatible Hue bulbs and fixtures directly to a Matter ecosystem - Apple Home, Amazon Alexa, or Google Home - while keeping them linked […]

It's unclear why Klue had not revoked the credential after the limited pilot, which hackers then used to breach a system holding keys for accessing customers' data.

The private events group, cofounded by Peter Thiel, says a “criminal” hacker is behind a breach that exposed members’ personal details. WIRED found no evidence a break-in was needed to access the files.
